Your Expert Guide to Layering Skin Care So It Actually Works

Caring for your skin is meant to be a calming, serene ritual. However, sorting out how to correctly layer all your serums, oils, and treatments can feel like a cognitive aptitude test, leaving even the savviest skin-care devotee furrowing their 11 lines in confusion.

As skin-care regimens have expanded (and expanded, and then expanded some more), they’ve grown increasingly complicated. Now, it’s standard to rotate products throughout the week and month, by season, and based on how skin is behaving on any given day. And, with every new supercharged serum or high-performance cream, there’s the question of where, exactly, does it belong in your routine? The vanity starts to feel like a skin-care chessboard, where you’re strategizing pieces for complexion victory.

The real challenge is getting everything to play well together on your skin, which isn’t easy when products have gotten so nuanced that it’s often hard to know which skin care category they fall under. A formula that looks like a moisturizer may be labeled a serum, but function as a peel. Is an emulsion a serum or a lotion? What’s more, nearly every product description insists it should be “applied first, before your other skin care.” This product sequence conundrum can lead to pilling (those little globules of skin care and makeup) or worse, irritated skin.

To clear up confusion, we asked top experts to explain exactly how to layer your skin care to get the most out of every formula.

Guidelines for preventing pilling and irritation

Nothing disrupts a perfectly executed beauty look faster than skin care balling up beneath your makeup. (Those gummy bits aren’t dead skin—they’re layered products clumping together.) It’s equally frustrating when your skin reacts to something in your regimen. Pilling and irritation are often caused by application mistakes, so before diving into how to order your routine, here are a few ways to ensure a calm, smooth finish.

1. Apply the right amount of product.

How often do you read, much less follow, a skin-care product’s recommended dosage? Slathering on a serum or treatment in excess might feel delicious in the moment, but it won’t speed up results—it’ll just fast-track problems. “Dosage directions are based on the safety and efficacy testing of a formula,” explains cosmetic chemist Ginger King, president and CEO of Grace Kingdom Beauty. “If you use more than the directions advise, your skin may react, and you’ll assume the problem is with the product, when really, you’re just overdoing it.”

Not to mention, your skin can only absorb so much formula, says board-certified dermatologist Dendy Engelman, MD, director of dermatologic surgery at New York Medical College. “At a certain point, it’s diminishing returns and a waste of time, money, and product,” she says. “The only skin-care item dermatologists want you to load on is sunscreen.”

2. Cap your leave-on products at four per routine.

Limit your a.m. and p.m. routines to four leave-on steps each. If you like using multiple serums or treatments, “just alternate them on different days or nights rather than layering them together,” says Mona Gohara, MD, a board-certified dermatologist and clinical professor in the Department of Dermatology at the Yale School of Medicine.

3. Wait 30 to 60 seconds between skin-care steps.

“This allows each formula to dry down and settle on the skin, which helps prevent balling,” says Gohara. Give it a beat between completing your skin care and starting your makeup, too—several minutes, if you can. Patience is a virtue and your best defense against pilling.

4. Check labels for exfoliating ingredients.

You can’t judge a product by its packaging. Plenty of skin-care items these days aren’t marketed as exfoliants but still contain exfoliating properties. Cleansers, toners, and moisturizers may contain glycolic acid, salicylic acid, lactic acid, or fruit enzymes, while vitamin C—which increases cell turnover—is in many antioxidant and brightening serums. Use more than one of these products at a time, and you can overexfoliate your skin without realizing it, triggering dryness and sensitivity (more on how to manage this below). For any formula marketed as purifying, refining, smoothing, or radiance-boosting, scan the ingredient list for the previously mentioned ingredients.

A step-by-step guide to layering skin care

In general, formulas with actives that treat the skin should go on first so they can absorb and do their magic, followed by moisturizers and protective barriers that seal in hydration. This usually means applying products in order from thinnest to richest, though we highlight a few exceptions below. Of course, what you use will depend on your skin type and concerns. So refer to this layering blueprint, but feel free to skip any non-essential steps (ahem, not sunscreen or a daily antioxidant serum) that don’t suit your needs.

STEP 1: Cleanse and exfoliate

Starting with a clean slate twice a day allows your skin care to fully absorb and work harder to deliver the best results. Even though you (hopefully) go to bed with clean skin, wash your face again in the morning. Many nighttime skin-care products contain ingredients that aren’t water-soluble, meaning any remnants won’t simply rinse away in the shower.

In the evening, to thoroughly dissolve cosmetics and SPF ingredients, use an oil-based cleanser such as a cleansing oil or balm. With other types of face washes, use an oil-based makeup remover or micellar water first.

A few times a week (or even daily if your skin can handle it), exfoliate after cleansing to clear away dead skin, which also helps your products absorb better and boosts your glow. Some people exfoliate at night, others prefer morning. You do you—just be sure you don’t apply more than one exfoliating formula at a time to avoid irritation. This means if you use a vitamin C product in the morning (and you should, as we’ll explain in a moment), save anything that contains alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs) for the evening.

OPTIONAL: Toner, essence, or mist

Feel free to spritz, splash, or swipe on these watery liquids to your heart’s content—most deliver hydration, antioxidants, and nutrients and feel wonderfully refreshing, so there’s no downside to them. Just know that modern skin care is designed not to disrupt the skin’s pH, so toners and essences aren’t an essential step.

“Toner was originally created to rebalance the skin’s pH after using the soapy, alkaline cleansers of the past,” explains King. “But today’s face washes are much gentler, so most people don’t need a toner.” The one exception, she says, is certain K-beauty and Japanese foaming cleansers, which can be high alkaline. “If it leaves your skin feeling tight afterward, follow with a toner labeled ‘balancing’ to reset the skin’s pH.”

STEP 2: Eye cream

Tend to the delicate skin around your eyes before you reach for your face products. (And if you use an exfoliating pad after cleansing, rinse your hands before applying.) “You want to apply eye cream first, while your fingers are clean,” says Gohara. “Facial skin care contains ingredients that aren’t supposed to go near your eyes, like retinoids and acids, so you don’t want those to get mixed in with your dab of eye cream.” 

Some richer eye creams can pill under concealer, so if that happens, “switch to a lightweight eye gel for daytime,” says King.

STEP 3 - MORNING: Antioxidant serum

A well-formulated antioxidant serum is a daily must—it’s the undercover hero of a morning routine, helping neutralize free radicals that speed up skin aging. If you want radiant skin—and who among us doesn’t?—choose a formula with vitamin C, which also smooths skin and brightens skin tone.

“Vitamin C and ferulic acid are a particularly effective pairing, which is why these two potent antioxidants are often combined in a serum,” says Engelman, noting that ferulic acid helps stabilize vitamin C to enhance its performance. SPF filters UV rays, while antioxidants help neutralize the free radicals they generate in the skin, maximizing your overall protection.

STEP 3 - EVENING: Treatment

While you sleep, your skin shifts into repair mode. “Cellular turnover and metabolic activity increase at night, making it the ideal time to apply actives that address lines, discoloration, and breakouts,” says Gohara.

If you’re using a retinoid, acne fighter, dark spot corrector, or any medicated treatment, apply it first on clean skin before serum or moisturizer. “You want your most potent, targeted formula in direct contact with your skin,” says Engelman.

There is one exception, according to King: “If your skin is sensitive or adjusting to a new treatment, you can apply a thin layer of moisturizer first as a buffer.

Remember, apply only one exfoliant at a time. Alternate a retinoid with any product that contains alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs) on different nights. And avoid layering benzoyl peroxide with retinoids or vitamin C, as this can make them less effective.

While treatments are typically reserved for the evening, if you want to level up your a.m. routine, apply a peptide serum. Peptides may soften the look of lines, increase firmness, and strengthen the skin barrier (the skin’s protective outer layer). They also layer well with most skin care, with one caveat: Copper peptides shouldn’t be applied alongside vitamin C, as it can reduce their efficacy.

STEP 4: Moisturizer

Moisturizer is like nourishment, softening and cushioning the skin. It also reinforces the barrier, so skin stays strong and can hold in water and actives. That’s why you shouldn’t skip moisturizer, even on the hottest days or if your complexion is oily. In those instances, go with a lightweight emulsion or gel-lotion.

On the flip side, if your skin needs more moisture, a hyaluronic acid serum layered under your lotion or cream delivers additional hydration without any heaviness. Its gel-like texture absorbs almost instantly, helping skin look and feel plumper. Hyaluronic acid can, however, pill under makeup—so for daytime, choose a serum with a velvety finish, as anything that dries slightly sticky or tacky is more likely to pill, says Engelman.

STEP 5 - MORNING: SPF

Sunscreen should always be the final step in your morning routine, regardless of whether it’s lighter weight than your moisturizer. In fact, even if your moisturizer contains broad-spectrum SPF 30 or higher, you still need a dedicated sunscreen on top of it. “You can’t rely on the SPF in moisturizer alone for daily protection,” says Gohara. “There may not be enough sunscreen ingredients in the formula, or they may be too diluted by other ingredients, to deliver the full SPF protection number listed on the bottle. Plus, indoor light can contribute to melasma and hyperpigmentation on all skin tones, so you want to adequately protect against light exposure in general every day with a standalone sunscreen.”

STEP 5 - EVENING: Face oil

At night, patting on a few drops of face oil helps lock in moisture and actives. Despite its liquid-y texture, oil goes on last because it’s occlusive, meaning it forms a physical barrier to seal in your other skin care and prevent water loss. Just remember that face oils don’t hydrate on their own—so while they’re not a replacement for moisturizer, they are its perfect bedtime companion.
